Active Directory. An implementation of LDAP directory services by Microsoft for use primarily in Windows environments. Its main purpose is to provide central authentication and authorization services for Windows based computers. AD also enables administrators to assign policies, deploy software, and apply critical updates to an organization.
Administrative State. The intention of the operator by setting a given resource up or down. See also Oper State.
Dynamic Host Configuration Protocol. Enables network devices to automatically obtain a valid IP address from a server.
Oracle’s EDR InfiniBand fabric. A 100-Gb converged fabric for network, storage, and interprocess communication.
The connections between the IB fabric and the data center LAN. Ethernet gateways present a collection of NICs to the Ethernet LAN.
Host channel adapter. An InfiniBand NIC used in an InfiniBand network. Provides high-speed connectivity and virtual interfaces, based on the IB interface. An HCA can have one or two ports.
A virtualization platform that enables multiple guest operating systems to run at the second level above the hardware.
Input/output. In computer architecture, the combination of the CPU and main memory (that is, memory that the CPU can read and write to directly, with individual instructions) is considered the "heart" of a computer. Any movement of information to or from that complex, for example to or from a disk drive, is considered I/O.
A single port on an Ethernet module, an HBA module, or one of the 38 IB server ports.
Lightweight Directory Access Protocol. An application protocol for querying and modifying directory services running over TCP/IP. A client starts an LDAP session by connecting to an LDAP server, by default on TCP port 389. The client then sends operation requests to the server, and the server sends responses in turn.
Maximum Transmission Unit. The largest physical packet size (in bytes) that a network can transmit. MTU values are only applicable to Ethernet ports, and the MTU of the I/O port must match the MTU of the neighboring switch.
N_Port ID Virtualization. A technology that defines how multiple virtual servers can share a single physical FC port identification.
Operative State. Indicates whether a resource is configured and operating properly. See also Admin State.
The fabric used to build and manage an Oracle cloud network infrastructure.
Private virtual interconnect. Connects the switch to the fabric and manages those Ethernet connections.
Remote Authentication Dial In User Service (RADIUS). An Authentication, Authorization, and Accounting (AAA) protocol for controlling access to network resources. RADIUS is commonly used by ISPs and corporations managing access to Internet or internal networks across an array of access technologies including modem, DSL, wireless, and VPNs.
Redundant Array of Independent Disks. A data storage virtualization technology that combines multiple physical disk drive components into a single logical unit for the purposes of data redundancy and performance improvement.
One of five fixed-privilege levels that a user may be assigned (such as, Operators, Administrators, or Storage).
One instance of a server I/O configuration that is assignable to a single physical server through an IB port.
Embedded subnet manager. SM groups manage and monitor the switching and pathing tables in an IB subnet. When there are multiple SMs on a subnet, one SM will be the master SM through an election algorithm. The remaining SMs become standby SMs. There is only one master SM per subnet.
Displayed in Oracle Fabric Manager and the CLI as a pair of statuses, for example: up/up. The first is the Admin State while the second is the Oper State. When using SNMP, these statuses are returned individually.
Configures all aspects of an IB fabric, including assigning LIDs to all HCAs and switch ports in the fabric, providing lookup service for end nodes, configuring program switch forwarding tables based upon the selected routing algorithm, and programming PKEY tables for HCAs and switches.
An internal or external representation of a person. Users exist locally through LDAP. By default, an admin user is created locally.
Virtual Host Bus Adapter. Connects a computer, which acts as the host system, to other network and storage devices.
Oracle Fabric Interconnect F2- Switch. This virtualization switch supports several I/O modules that provide FC and Ethernet connectivity.
Virtual local area network. A private, independent, logical network that is created within a physical network. A VLAN behaves like an ordinary LAN, but connected devices don't have to be physically connected to the same network segment.
Virtual machine. A software entity that runs its own operating systems and applications, as if it were a physical computer. A VM behaves exactly like a physical computer and contains its own virtual (software based) CPU, RAM, hard disk, and NIC. An OS installed on a VM is called a guest operating system.
